OK this one is a bit off the wall but MartyB and I had 2 days to talk about it driving home from the CON and we both thought this idea would be cool.
How about once a month or so, enable all the "special" planes in the game. RV-8, flying PT boats, Santa, and whatever else you guys might have easter egged in the game. Call it HELL NIGHT and when it goes active all scores are turned off, kill shooter is turned off, night time is turned on, ENY is out the window, and let chaos rule the MA for a 24 hour period. Maybe even do up a special map for it or something. Allot of people were complaining about the RV-8's and not being able to fly them, so why not give everyone a taste from time to time. Don't anounce when your going to do it, just turn it on at random every 30 days or so. Keep people guessing as to when it's going to happen. It would give everyone a little break from the same old, same old, MA style of play.
Besides HiTech, you said best. "It's all about pissing the other guy off!"
